My initial experiment with BirdDog NDI TV Monitor for Android on the Tivo Stream 4K turned in less than stellar results, but it did generate some interest amongst NDI users online. I accept that the Tivo device is a somewhat vintage host platform.
One person mentioned that Birddog had presented the application at NAB 2023 running on a current generation of Chromecast. I haven’t had a Chromecast since it was first introduced. It certainly is the definitive Android TV device. So, I bought a brand new Chromecast with Google TV. The very latest version capable of 4K & HDR.
This latest Chromecast has only two connectors: HDMI for connection to the TV, and USB-C for power.
